Thinking of new tires for my Trek 610. It’s had Challenge Strada Bianca 700x30 (I think - they measure 31.5 mm) and I’d like to go to 38 mm. The chainstay limit wold easily be big enough if there were dimples, but I have to check the brakes and bridges before i cold-set anything.

Has anyone done this? What kind of tool is used for the crimping?
